The parotid gland is the largest pair in the salivary gland, the majority attached to the mandibular posterior fossa under the earlobe, the front part is located on the surface of the chewing muscle, reaching the lower edge of the zygomatic arch, the surface of the parotid gland covered by the skin and neck superficial fascia, deep and Sternocleidomastoid and mastoid adjacent. Parotid gland saliva through the parotid duct to the mouth. Parotid duct length of about 5 to 6 cm, diameter of about 0.2 to 0.3 cm at the front of the gland issued at the upper end of the line to the front of the masseter muscle, at right angles through the buccal muscle, opening in the maxillary second molar relative Buccal mucosa. Common parotid swelling can be divided into two categories of inflammation and cancer, of which
